Very interesting information especially found this to be informative:
Frontal Lobes: The frontal lobes functioning together are seen by many to be the abstract problem solving regions of the cortex. And, indeed, this statement is generally true—especially when one is contrasting the functional capabilities of these two regions with those of the posterior regions. Nonetheless, when looked at in detail and compared with each other, it is also clear that while both actively solve problems, they excel at solving quite different problems. Moreover, this difference in “what they do well” is directly linked to key differences in how they function
The frontal lobe on the left side seems to function in a manner which allows it to measure precisely and process logically. Mental tasks which we identify as: functional analysis, critical analysis, prioritizing, comparative analysis, cost/benefit analysis, identifying key factors, assigning a weight or value to each factor, identifying desirable strategic alliances, all of which use both logic and precise measurement, are readily accomplished by the frontal left, especially when the problem is one of correcting something that was at one time, but no longer is, functioning adequately; improving efficiency or functioning; fixing something that has been fixed before, successfully, making a logical, next-step improvement to an existing procedure, process or machine. As such, the frontal left lobe appears to be the home base for Jung’s Thinking Function.
By contrast the frontal lobe on the right side seems to function in a manner which allows it to see patterns and trends as well as use its imagination. Mental tasks which we identify as: pattern recognition, perception of trends, spatial rotation, creating or inventing new solutions — all of which are readily accomplished by the frontal right, especially when the problem is one of which is difficult to solve, has never been solved before, involves change and dynamic systems, and or in which all the data can never be known. As such, the frontal right lobe appears to be the home base for the Function Jung called Intuition.
I will think more on your education question. However, I seriously doubt that the goal is educating everybody equally in the good ol US. I doubt that efficiency has ever been the goal and that for the most part, our efforts to educate have been aimed at cranking out the factory workers. One would have to assume that somehow the emphasis had shifted--you only need to look at the level of funding for education to see that it isn't a priority.
